A champagne tower-type multi-stage throttle control valve includes a valve body, a valve cover, a throttle sleeve, and a valve core. A sleeve cavity of the throttle sleeve is shaped as a stepped hole with two or more layers. The valve core is shaped as a stepped shaft with two or more layers coaxial with the throttle sleeve. The number of shaft shoulders of the valve core is smaller than or equal to the number of hole shoulders of the sleeve cavity of the throttle sleeve, such that each set of shaft shoulders of the valve core in an axial direction can form a sealing surface fit with corresponding hole shoulders of the throttle sleeve. A flow channel groove is axially or obliquely formed on each of the hole shoulders of the throttle sleeve and/or the shaft shoulders of the valve core.

Abstract

A heat dissipation system for a high-speed train running in a low-vacuum tube is provided. Component groups that provide power and resistance for the movement and stop of a train are provided at a periphery, close to the train, in a low-vacuum tube. The component group is provided with a group A cooling assembly. The group A cooling assembly includes a group A cooling-type heat exchanger and/or a group A nozzle assembly attached to the back of the component group. Since the friction between the train running at high speed and the air in the low-vacuum tube and the operation of the key equipment in the low-vacuum tube will generate a lot of heat, the group A cooling assembly in the component group in the low-vacuum tube exchanges the heat with the air in the low-vacuum tube.

The appearance of a sleeve cavity of the throttling sleeve (30) is in a stepped hole shape having two or more layers, and the appearance of the valve element (40) is in a stepped shaft shape that has two or more layers and that is coaxial with the throttling sleeve (30). In addition, the number of shaft shoulders (41) of the valve element (40) is less than or equal to the number of hole shoulders (31) of the sleeve cavity of the throttling sleeve (30). Therefore, in the axial direction, each shaft shoulder (41) of the valve element (40) may form a sealed surface fit with the corresponding hole shoulder (31) of the throttling sleeve (30). A runner groove (a) is axially or obliquely formed in the hole shoulder (31) of the throttling sleeve (30) and/or the shaft shoulder (41) of the valve element (40). The champagne tower type multi-stage throttling control valve has a compact and simple structure and high action reliability, and thus, the difficulty and costs of machining the valve are reduced.
